Fix if Fingerprint Scanner not working or Not Detecting in OnePlus 8 Pro
Clean the screen
As OnePlus 8 Pro features an under-display fingerprint sensor, so the first step would be to completely clean the screen with any microfibre cloth. Technically, the presence of dust, smudge, or dirt on the screen would have little effect on your device’s fingerprint scanner as it uses sound in scanning a 3D image of a finger. However, real-world tests show otherwise.
Remove the screen protector
If you’re using a screen protector, try to remove it and see if the fingerprint scanner starts working again. Poorly installed or low-quality screen protectors may degrade the scanner’s capability. If nothing works, continue with the troubleshooting steps below.
